The buckle includes: at least three laminate plates, a movable latch means, a manually operable actuation means, and a no false latch biasing means. The biasing means includes: a tongue engaging portion which may be at least one upper arm, an energy storage means which may be at least one coil torsion spring, and a latch engaging portion which may be at least one lower arm. The biasing means moves the latch means into engagement with the tongue when the tongue is substantially inserted in the buckle and ejects the tongue upon movement of the latch means by the actuation means. The buckle offers low resistance to insertion of the tongue until the tongue nears its fully inserted position and thereby avoids a problem of "false latching".
